I'd rate them as very soft lenses. Comparing them to my Bronica MC lenses, I find them to be softer overall. They are sharp enough, but the colors seem to be a bit muted when compared to the MCs. Not that this is bad. These are GREAT portrait lenses, and very nice when you want to tone things down a bit. Honestly, the results seem similar to some of the LF lenses I have seen (which tend to be more "vintage".
The ability to get in close is great though (adjust for parallax though! and there is nothing stopping you from taking a GREAT picture with theses lenses.
